This invention exhibits the following effects peculiar to this invention by providing the structure as mentioned above.

1. The ejector of this invention can improve the function which prevents illegal use. The cosmetic solution equipped with this ejector can be safely and reliably transmitted to the user.

2. Since the stopper attached to the lower part of the lowering head in the unused state is covered with the cover of the outer cap, the stopper cannot be released unless the cover of the outer cap is removed. Then, by fitting the outer cap and the inner cap, a structure in which the outer cap cannot be removed from the inner cap is realized.

3. In the state in which the ejector is attached to the container, the ejector cannot be detached from the container, so that the entire ejector cannot be removed. Therefore, the retention function in the unused state can be improved, and mixing of heterogeneous substances can be prevented even after opening.

4. The stopper provided between the pressing head and the top wall of the inner cap so as to be detachable is covered with the cover of the outer cap, and the outer cap body portion is externally fitted to the inner cap. It is held by the engagement to the inner cap by the engaging portion of the container, and detachment prevention means for preventing the removal of the inner cap from the neck of the container is provided between the inner cap and the outer cap. For this reason, the outer cap cannot be removed from the inner cap by fitting the inner cap and the outer cap, and at least the cover portion of the outer cap is removed so that the stopper can be removed, and the stopper is pressed between the lowering head and the top wall portion of the inner cap. If it is not removed, the pressing head is pushed down, and the liquid contained in the container cannot be discharged from the discharge hole. In particular, when the cover portion of the outer cap is removed and the stopper can be removed, it is not possible to return the cover portion of the outer cap to the state before removal or removal. Can be reliably prevented, and the ejection of the liquid from the container in the unused state can be prevented reliably, and the unused state can be ensured.

5. When the inner cap is screwed to the neck of the container, the inner cap is covered by the outer cap, so that torque cannot be transmitted directly to the inner cap, and the torque applied to the outer cap reaches the inner cap through the ratchet mechanism. When the outer cap is rotated in the direction of joining the inner cap to the neck portion of the container, the inner cap and the outer cap engage with the ratchet mechanism, and the inner cap rotates together with the outer cap. If possible, however, when the outer cap is rotated in the direction of releasing the screwing of the inner cap to the neck of the container, the inner cap and the outer cap are not engaged by the ratchet mechanism, and the outer cap is idling. Therefore, since the inner cap cannot be removed from the neck of the container unless the outer cap is removed from the inner cap, the unused state can be more reliably maintained.

6. By removing the cover portion of the outer cap from the main body portion of the outer cap, the cover portion of the outer cap is separated along the weak portion, so that the stopper is in a removable state. Therefore, by removing this stopper, it will be in the state which can push down a down nozzle, and will be in the state which can discharge the liquid accommodated in the container. As a result, after the outer cap is removed along the fragile portion in the unused state, the outer cap cannot be returned to the state before the outer cap is removed. Therefore, the unused state can be more reliably maintained, and the unused state after the use state is once used. It is possible to reliably prevent the return to the furnace.

7. The locking torque of the ratchet mechanism when the lock mechanism is installed between the neck and the inner cap of the container and rotated in the direction of mounting the inner cap on the neck of the container is the lock mechanism when the inner cap is attached to the neck of the container. When the locking torque of the ratchet mechanism is larger than the locking torque and rotated in the direction of removing the inner cap from the neck of the container, the locking torque of the ratchet mechanism is smaller than the release torque when the inner cap is detached from the neck of the container against this lock mechanism. When the outer cap is rotated in the direction of joining the inner cap to the neck of the inner cap, the inner cap and the outer cap engage with the ratchet mechanism, so that the inner cap can be rotated together with the outer cap, and the neck and the inner cap of the container can be engaged with the locking mechanism. At the same time, it is more difficult to remove the inner cap from the neck of the container compared with the case where the inner cap is provided without the locking mechanism on the neck of the container. Therefore, in addition to the prevention of the detachment of the inner cap by the ratchet mechanism, the neck portion of the container may be adjusted by the torque balance between the engagement torque in the apparatus direction by the ratchet mechanism, the engagement torque in the detachment direction, and the engagement torque and release torque by the lock mechanism. It is possible to more reliably prevent the removal of the inner cap from 22).

8. The stopper is located under the fall prevention rib provided on the upper side of the cylinder and is covered by the cover of the outer cap, so that the stopper cannot be pulled out even when the pressing head is pulled out. Can be. Therefore, even if the pull-down head is removed from the top of the stem of the pump, as long as the cover part of the outer cap is not removed, the fall prevention rib is obstructed and the stopper cannot be pulled upward, so after removing the push-down head again, By providing the depressing head, it is possible to reliably prevent the depressing head from being pushed down, thereby making it possible to more surely maintain the unused state.

9. The outer circumferential surface of the protruding super cylinder portion covering at least a portion of the stem protruding upwardly from the communication hole and the inner circumferential surface of the depression concave portion of the depressed head of the depressed head into which the protruding fighting tube portion is depressed are formed by pressing in a polygonal cross section in the radial direction. It becomes possible to position the direction of the lowering head. For this reason, by positioning the direction of this push down head, a container can be made directional and the assembly process of an outer cap becomes easy. In addition, since the nozzle direction of the push-down head can be changed and fixed at that position by the elastic deformation of the resin as the member, the position of the residual liquid and the suction tube can be specified. It becomes possible to use all the contents liquid. In addition, since the front and back sides can be determined, the position of the pasting of labels and the like can be specified, and when the plurality of containers are displayed, all the pushing heads can be easily aligned in one direction.

10. At least a part of the stem protruding upward from the communication hole is covered with the protruding fighting barrel portion 39, and a stopper provided with a fall prevention rib is provided in the protruding super cylindrical portion. For this reason, when the push down head is removed and the liquid contained in the container is drawn out from the top of the stem, and then the top of the stem is intended to be put back on the push down head, the top of the stem goes into the protruding barrel of the inner cap. As we cannot put down nozzle in the upper part of this stem again and cannot return to unused state, we can make sure of unused state more surely, and we removed push down nozzle and took liquid from container It is possible to more reliably prevent the return to the unused state later.

11. A container equipped with an ejector can be kept in an unused state before opening, and it is difficult to mix foreign matters after opening, so that the remaining amount can be minimized.

This invention is installed in the neck part of the container which accommodated the liquid, and the cylindrical main wall part joined to the neck part of the container which provided the communication hole which communicates with the mouth part of this container, and the neck part of the container which covers the periphery of this ceiling wall part. An inner cap having a section, a pump inserted into the communication hole of the inner cap, and having at least a portion of the stem inserted into the communication hole of the inner cap so as to be moved downward from the upper side and protruding upward from the communication hole, and the stem of the pump. An ejector having a depression head having a nozzle portion formed at an upper end of the ejection hole, the ejector comprising a stopper for preventing the depression of the depression head from being interposed between the depression head and the top wall portion of the inner cap so as to be detachable. The cover part which covers this stopper, the cylindrical main body part externally fitted to an inner cap, and the engaging part engaged with this inner cap when this main body part is externally fitted to an inner cap It has the outer cap which has. The cover portion of the outer cap is provided with a cutout portion for avoiding contact of the pressing head with the cover portion by the nozzle portion when the outer cap is mounted from the lowering head side, and between the inner cap and the outer cap, from the neck portion of the container. Peel-off prevention means for preventing detachment of the inner cap is provided. If the outer cap cannot be detached from the inner cap by fitting the outer cap and the inner cap, at least the cover portion of the outer cap is removed, and the stopper can be removed, and if the stopper is not removed from between the lowering head and the top wall portion of the inner cap, The pressing head is pushed down, and the liquid contained in the container cannot be discharged. In particular, when the cover portion of the outer cap is removed and the stopper can be removed, the cover portion of the outer cap cannot be returned to an unused state before the cover portion is removed or removed.

In the ejector of the present invention, when the inner cap and the outer cap are engaged with each other in the direction of joining the inner cap to the neck of the container, the inner cap and the outer cap rotate together, so that the inner cap can be more reliably attached to the neck of the container. On the other hand, when it rotates relatively in the direction which releases the screwing of the inner cap to the neck part of a container, an inner cap and an outer cap do not engage, and an outer cap idles. Therefore, this inner cap cannot be removed from the neck of the container unless the outer cap is removed from the inner cap. By removing the locking portion of the outer cap from the main body portion of the outer cap and separating the outer cap along the weak portion, the cover portion of the outer cap can be removed from the inner cap, and the stopper can be removed. In this state, the stopper can be pushed down to remove the stopper, and the liquid contained in the container can be discharged. Cannot be returned to its state before separation.

The discharging machine of the present invention has an engagement torque of the ratchet mechanism when a lock mechanism engaged when the inner cap is attached to the neck portion of the container is provided between the neck portion and the inner cap of the container, and rotated in the direction in which the inner cap is attached to the neck portion of the container. Is set larger than the engagement torque of the lock mechanism and smaller than the release torque when the inner cap is detached from the neck of the container in response to the lock mechanism. When the outer cap is rotated in the direction of joining the inner cap to the neck of the container, the inner cap and the outer cap engage with the ratchet mechanism, so that the inner cap can be rotated together with the outer cap, and the neck and the inner cap of the container can be engaged with the locking mechanism. have. In comparison with the case where the inner cap is engaged with the neck of the container, it is more difficult to remove the inner cap from the neck of the container. Therefore, in addition to preventing the removal of the inner cap by the ratchet mechanism, the torque balance between the engagement and release torque by the lock mechanism As a result, detachment of the inner cap from the neck of the container is more reliably prevented.

The depression head of the ejector of this invention is provided with the recessed part which accommodates the front end side of the protruding super cylinder of an inner cap. By devising resistance means for preventing free rotation of the relationship generated by the storage, the positional relationship between the two can be defined, and the direction of the nozzle and the like can be specified. As a means of this, a mechanism in which both of the polygons of hexagonal shape and polygons are formed and vertical ribs are formed on both sides in contact with the case where the depressed head is rotated to generate an interference resistance can be provided. This interference resistance is set to such an extent that it can be overcome by the general public, and it is set as the setting which ensures the convenience at the time of use.

The polygon will be described as an example. The ejector of this invention is each formed in the radial cross-sectional polygonal shape of the outer peripheral surface of the protrusion cylinder part which covers at least one part of the stem which protruded upwards rather than the communication hole, and the inner peripheral surface of the recessed recess part which this protrusion cylinder part is penetrated. Since the direction of the push down head can be positioned, the liquid contained in the container can be discharged without leaving more reliably, and the container can be oriented, for example, the position of the adhesive such as a label can be specified. When the plurality of containers are displayed, it is possible to easily adjust the directions of all the depressing heads in one direction. Here, the outer circumferential surface of the protruding super cylinder portion and the inner circumferential surface of the indentation recessed portion are preferably polygonal with a hexagonal cross section of a radial section or more so that the pressing head can rotate in the circumferential direction when a predetermined force is applied, and the radial section octagon is more preferred. desirable. In addition, even when the pulling head is removed from the upper end of the stem of the pump, the stopper cannot be removed by the cover portion of the outer cap, and the stopper cannot be pulled upward by the release preventing rib. After removing the stopper after removing it, the lowering head is mounted again so that the lowering head cannot be pushed down.

The ejector of this invention is provided with the fall prevention rib in the cylindrical protrusion cylinder part which covers at least one part of the stem which protruded upwards rather than the communication hole, and a stopper is provided in this protrusion cylinder part, and a push-down head is removed and a stem is removed. After the liquid contained in the container has been withdrawn from the top of the top of the stem, the top of this stem is pushed down again on the top of the stem as the top of the stem enters into the protruding top of the inner cap if the head is to be remounted. The nozzle cannot be mounted and cannot be returned to an unused state. In addition, although a stopper is provided in the protruding super cylinder portion of the inner cap, but the protruding super cylinder portion is not formed and the stem of the pump is not exposed or covered, it is also possible to have a structure in which a stopper is attached to this stem. .

1. Container

The container can determine the size suitably according to the use and the capacity | capacitance of the liquid accommodated. In this container, liquid, such as cosmetics, is accommodated, for example, and the mouth part for accommodating or taking out a liquid in this container is provided in the upper end part. It is preferable that some or all of the containers are transparent so that the remaining amount is visible. The contained liquid is drawn off from the tube mounted at the bottom of the pump.

2. My cap

)형상의 통체(筒體)를 형성할 수 있다.The inner cap is provided with a female screw to be screwed into the neck portion of the container, and a communication hole for mounting a pump is provided in the center portion. Also, the inner cap is thicker to cover the stem by directing upwards.

) Can be formed into a cylindrical body.

The inner cap is provided in the neck portion of the container, and a communication hole communicating with the bent portion of the container is provided in the ceiling wall part. The cylindrical main wall part which sticks to the neck part of a container is provided. Moreover, the cylindrical protrusion super cylinder part is provided in the part between the top wall part of an inner cap, and a depression head. On the outer circumferential surface of this projecting fighting barrel part, the fall prevention rib which prevents falling out of the stopper in the state which removed the down head from the stem of a pump can be provided. The outer peripheral surface of this protruding super cylinder part can be formed in cross-sectional polygonal shape. It is also possible to provide a lock mechanism that engages between the inner cap and the neck of the container when the inner cap is attached to the neck of the container. The lock mechanism is preferably set so that the engagement torque when the inner cap is attached to the neck of the container is smaller than the release torque when the inner cap is detached from the neck of the container against the lock mechanism.

3. Pump

The pump is inserted into the communication hole of the inner cap and is installed, and protrudes a part of the stem inserted through the urging from above to move downward from the communication hole. Moreover, at least one part of this stem which protrudes above the communicating hole is covered with the protruding super cylinder part of an inner cap. The lowering head is mounted on the top of the stem.

4. Pressing down head

The depressing head has a nozzle portion in which a discharge hole is formed, and is mounted in close contact with the upper end of the stem of the pump. In the case of contacting the protruding super cylinder portion of the inner cap, a depression concave portion is formed in which the protruding super cylinder portion of the inner cap is inserted when the depressed head is pushed down.

5. Stopper

The stopper is for holding down the down head of the down head and maintaining the unused state. The stopper is detachably mounted between the down head and the ceiling wall portion of the inner cap in the unused state. The stopper is a cylindrical shape in which a notch is formed in the longitudinal direction covering the protruding super cylinder part of the stem or the inner cap, and can be detached by passing it through the notch. In the case where the protruding super cylinder portion is formed in the inner cap, the protruding super cylinder portion is provided so as to be detachable from the outer peripheral surface of the protruding super cylinder portion. In the case where the protruding super cylinder portion is polygonal, the stopper end face inner peripheral surface is formed into a polygonal cross section. Rotation of the stopper is controlled by the polygon. In addition, when used, the stopper is removed.

6. Outer cap

The outer cap has a cover portion covering the stopper, a cylindrical main body portion that is externally fitted to the inner cap, and an engagement portion that is engaged with the inner cap when the main body portion is externally fitted to the inner cap. The cover portion is provided with a cutout that prevents contact of the pressing head with the cover portion by the nozzle portion when the outer cap is mounted from the pressing down head side. Between the outer cap and the inner cap, a peeling preventing means for preventing peeling of the inner cap from the neck portion of the container is provided. The peeling preventing means is preferably a ratchet mechanism, in which the inner cap and the outer cap are engaged in rotation in the direction of fitting the inner cap to the neck portion of the container, so that the inner cap can be rotated together with the outer cap. On the other hand, after the container is attached to the neck, in the case of relative rotation in the direction of releasing the screwing of the inner cap, the ratchet mechanism is configured such that the outer cap is idle. The engagement torque of the ratchet mechanism is set larger than the engagement torque of the lock mechanism when the inner cap is attached to the neck of the container. When the inner cap is detached from the neck of the container against this lock mechanism, the ratchet does not match and the release torque does not act on the lock.

The cover part is separated from the main body part at the time of use, and can approach a stopper. A weak part is formed between a cover part and a main body part in the circumferential direction, and it is set as the structure which can be separated from the weak part.

A bent piece is provided on the side of the cutout portion provided in the cover portion, and can be formed as a handle portion or a handle at the time of removing the cover portion.

7. How to assemble

Attach the lowering head to the top of the stem of the pump mounted in the communication hole of the inner cap. Thereafter, a stopper is provided between the pressing head and the ceiling wall portion of the inner cap so that the pressing head cannot be pushed down. When the protruding super cylinder portion is formed in the inner cap, the stopper is attached to the outer surface of the protruding super cylinder portion. At this time, it is difficult for the depressing head to receive the release preventing rib provided with the inner cap on the protruding supercylinder to the recessed concave portion, thereby making it difficult to pull out the stopper upward.

The outer cap is then piped to the inner cap. The cutting portion provided in the cover portion of the outer cap allows the nozzle of the lowering head to pass through, so as to externally fit the main body portion of the outer cap to the inner cap, and to engage the ratchet mechanism between the outer cap and the inner cap. Further, a tube for sucking is installed at the lower end of the pump, the lower end of the pump is inserted into the bent part of the container in which a predetermined amount of liquid is accommodated, and the outer cap is rotated to join the main wall of the inner cap to the neck of the container. The neck and the inner cap of the container are engaged with the locking mechanism to be an unused ejector.

8. How to use

When the discharger in an unused state is brought into a normal use state in which the liquid is discharged by pressing down the pressing head, the cover portion of the outer cap is removed along the fragile portion and removed. At this time, when the cover part of this outer cap is removed, it becomes a state which a stopper can remove. By removing this stopper, the pressing head is pushed down, and the liquid contained in the container can be discharged. Thus, in normal use, the stopper cannot be removed unless the cover of the outer cap is removed.

However, it is also possible to pull out the lowering head of the ejector with full power, and forcibly remove the lowering head from the top of the stem of the pump, and take out the liquid contained in the container from the top of the stem of the pump. If you remove the lowering head from the top of the stem, and then put the lowering head back on the top of the stem, the lowering head is pushed into the protruding top of the inner cap, so this lowering nozzle is Cannot be installed again and cannot be returned to an unused state. In addition, since the stem and the down head are mounted in a close state in a sealed state so that there is no liquid leakage, the mounting of the down head needs to be performed while the stem is pressed down and fixed.

When the inner cap is removed from the neck of the container and the liquid in the container is to be taken out from the bent part of the container, the inner cap cannot be operated directly because the outer cap is fitted to the inner cap and the outer cap is provided. If the inner cap is to be rotated in the direction of releasing the inner cap of the inner cap to the neck of the container through the outer cap, the ratchet mechanism provided between the inner cap and the outer cap prevents the outer cap from engaging with the inner cap and the outer cap is idle. The inner cap cannot be removed from the neck of the container.

In addition, when the inner cap is rotated in the direction of mounting the inner cap to the bent portion of the container via the outer cap, these inner caps and the outer cap are engaged with the ratchet mechanism, and the inner cap rotates together with the outer cap, and the neck portion of the container is rotated. The inner cap can be combined more securely and installed.

The container of the present invention is suitable for a container for preventing the mixing of foreign substances after illegal use or opening, such as a cosmetic container or a medical container.

The inflated portion 32c of 3) is held in close contact with each other, and the inclined surface 38a of each ratchet tooth 38c of the ratchet member 38 of the inner cap 3 and the ratchet member 72 of the outer cap 7 are held. The inclined surfaces 72a of the respective ratchet teeth 72c in mesh with each other to engage. In addition, the cover cylinder portion 76 of the outer cap 7 covers the stopper 6 provided in the protruding super cylinder portion 39 of the inner cap 3 over the circumferential direction, and removes the stopper 6. Covered so that

In this state, the lower end side of the pump main body 41 of the pump 4 is inserted into the bent portion 23 of the container 2 in which the liquid L is filled in a predetermined amount, and the After the inner cap 3 is externally fitted to the neck portion 22, the outer cap 7 is rotated to screw the female screw 33 of the inner cap 3 onto the male screw 24 of the container 2. The center piece 26a of each latching piece 26 of the container 2 is engaged with the ratchet tooth 36c of any of the latching ratchets 36 of (3), and it locks with the locking mechanism 35, FIG. It is set as the closed container 11 of the unused state shown to (a). At this time, by the ratchet mechanism 37 composed of the ratchet member 38 of the inner cap 3 and the ratchet member 72 of the outer cap 7, the female screw 33 of the inner cap 3 and the outer cap 7 are provided. Rotation in the direction of releasing the screwing of the male screw 24 of the container 2 becomes impossible, and detachment of the inner cap 3 from the bend 23 of the container 2 is prevented.

<Use>

A method of using the ejector 1 of this embodiment will be described. The ejecting head 1 of the closed container 11 in the unused state shown in Figs. 1A and 1B is pushed down by the push down head 5, thereby In a normal use state in which the liquid L can be discharged by a predetermined amount from the discharge hole 55a, a finger or the like is held on the bent piece 77 of the outer cap 7, and the bent piece ( 77) is removed from the cap main body 71 of the outer cap 7, and the covering cylinder portion 76 of the outer cap 7 is separated in the circumferential direction along the weak portion 77b, and the covering cylinder portion 76 is outer cap. It removes from the cap main body 71 of (7). At this time, the covering cylinder portion 76 of the outer cap 7 is removed from the cap body 71, so that the stopper 6 can be removed from the protruding super cylinder portion 39 of the inner cap 3 in the radial direction. By pressing the guide rib 63 in the direction in which the stopper 6 is removed, the main body portion 61 of the stopper 6 is elastically deformed, and the insertion opening 62 is expanded, so that the stopper 6 is capped. It detach | separates from the protruding super cylinder part 39 of (3). As a result, this stopper 6 is detached from the protruding cylinder part 39 of the inner cap 3, and it becomes the state which can push down the down head 5, and this down head 5 is removed. By pressing down, the liquid L contained in the container 2 is discharged from the discharge hole 55a of the lowering head 5 by a predetermined amount by the pumping operation by the pump 4 do.

Prevention of remounting of the press head when not in use

Pull down the lowering head 5 from the ejector 1 of the closed container 11 in an unused state, and forcibly remove the lowering head 5 from the upper end of the stem 42 of the pump 4. It is also assumed to take out the liquid L from the upper end of the stem 42 in which this pushing head 5 was equipped by taking out. In this case, however, if the pressing head 5 is detached from the upper end of the stem 42 and the lowering head 5 is pushed down to the upper end of the stem 42 to be mounted again, the stem ( 42 enters into the protruding cylindrical portion 39 of the inner cap 3 against the elastic force of the built-in spring mechanism, and the stem 42 to a position where the lowering head 5 can be mounted on the top of the stem 42. Before pressing down), the lower end of the main surface portion 53 of the lowering head 5 is brought into contact with the upper end of the main body portion 61 of the stopper 6, so that the lowering head 5 is further pushed down. Since it becomes impossible, this pushing head 5 cannot be mounted again on the upper end of the stem 42, and cannot be returned to an unused state. In addition, in the case where the pressing head 5 is detached from the upper end of the stem 42, the protruding second rib 39c is provided by an upper release preventing rib 39c provided in the protruding cylindrical portion 39 of the inner cap 3. Since the stopper 6 provided in the cylinder part 39 cannot be pulled out upward, after removing this stopper 6, the lowering head 5 is mounted again on the upper end of the stem 42, and this pushing head ( 5) It is also impossible to press down to make it operable.

<Prevention of detachment of inner cap in nonuse>

The inner cap 3 of the ejector 1 of the sealed container 11 in the unused state is detached from the bend 23 of the container 2, and the liquid in the container 2 is removed from the bend 23 of the container 2. (L), the inner cap (3) is externally fitted to the inner cap (3), and the outer cap (7) is provided, so that the inner cap for the external thread (24) of the container (2) via the outer cap (7) ( The inner cap 3 must be rotated in the direction of releasing the screwing of the female screw 33 of 3). In this case, the inclined surface 36a of each ratchet tooth 36c of the ratchet member 38 of the inner cap 3 The inclined surface 72a of each ratchet tooth 72c of the ratchet member 72 of the outer cap 7 abuts, and each ratchet tooth 36c of these ratchet members 38 and the ratchet member 72 of the outer cap 7 Each ratchet tooth 72c does not engage, and the outer cap 7 is in an idle state, and thus the inner cap 3 cannot be removed from the bend 23 of the container 2. On the other hand, when the inner cap 3 is rotated in the direction in which the female screw 33 of the inner cap 3 is screwed to the male screw 24 of the container 2 via the outer cap 7, the inner cap 3 is formed. The vertical surface 36b of each ratchet tooth 36c of the ratchet member 38 of the ratchet member 38 and the vertical surface 72b of each ratchet tooth 72c of the ratchet member 72 of the outer cap 7 abut, and the ratchet teeth of both members Since the inner cap 3 can be rotated together with the outer cap 7, the inner cap 3 can be more securely screwed into the bent portion 23 of the container 2 so that the inner cap 3 can be assembled.

<Virgin holding function>

In this embodiment, the stopper 6 which prevents the depressing operation of the depressing head 5 of the ejector 1 is provided in the protruding cylindrical part 39 of the inner cap 3, and this stopper 6 The state in which the cap body 71 of the outer cap 7 is externally fitted to the main surface portion 32 of the inner cap 3 is covered with the covering cylindrical portion 76 of the outer cap 7. The ratchet mechanism 37 formed between the inner cap 3 and the outer cap 7 is prevented from being held out by engagement with the lower edge of the main surface portion 32 of the inner cap 3 by the engaging rib 74. As a result, detachment of the inner cap 3 from the bent portion 23 of the container 2 is prevented. For this reason, in the unused state, the outer cap 7 cannot be removed from the inner cap 3, and at least the covering cylinder portion 76 of the outer cap 7 is removed, and the stopper 6 can be removed. If the stopper 6 is not removed from the protruding cylindrical portion 39 of the inner cap 3, the pressing head 5 is pressed down to press down the liquid L contained in the container 2. It cannot discharge from the discharge hole 55a of the head 5. At this time, when the covering cylinder portion 76 of the outer cap 7 is removed and the stopper 6 is detachable, the coating cylinder portion 76 of the outer cap 7 is in an unused state before being removed. Since it cannot be reversed, the removal of the stopper 6 and the removal of the inner cap 3 in the unused state can be reliably prevented, and the ejection of the liquid from the container 2 in the unused state, so-called test use Can be reliably prevented and the unused state can be reliably maintained.

In particular, the ratchet mechanism 37 formed between the inner cap 3 and the outer cap 7 screws the female thread 33 of the inner cap 3 to the male screw 24 of the container 2 via the outer cap 7. In the case where the inner cap 3 is rotated in the direction to be made, the vertical face 36b of each ratchet tooth 36c of the ratchet member 38 of the inner cap 3 and each ratchet tooth of the ratchet member 72 of the outer cap 7 The vertical surface 72b of 72c abuts, and each ratchet tooth engages, and the inner cap 3 can be rotated with this outer cap 7, and the neck part 22 of the container 2 can be rotated. The inner cap 3 is more securely screwed together to allow an operation for mounting. On the other hand, the ratchet mechanism 37 rotates the inner cap 3 in the direction of releasing the screwing of the female screw 33 of the inner cap 3 to the male screw 24 of the container 2 via the outer cap 7. In this case, the inclined surface 38a of each ratchet tooth 38c of the ratchet member 38 of the inner cap 3 and the inclined surface 72a of each ratchet tooth 72c of the ratchet member 72 of the outer cap 7 In contact with each other, the ratchet teeth are not engaged, and the outer cap 7 is idle. For this reason, if the inner cap 3 cannot be removed from the bend 23 of the container 2 via the outer cap 7, and this outer cap 7 is not removed from the inner cap 3, this inner cap 3 The inner cap 3 cannot be detached from the bend 23 of the container 2 by releasing the screwing of the container 2 into the male screw 24 by the female screw 33 of).

In addition, after separating the covering cylinder portion 76, which is the stopper cover of the outer cap 7 of the closed container 11 in the unused state, along the weak portion 77b, returning to the unused state before removing the outer cap 7 Since it becomes impossible to hold | maintain, the holding | maintenance of the airtight container 11 of the unused state can be made more reliably, and returning to the unused state after making it into use state can be prevented reliably.

Moreover, the lock mechanism 35 is formed by the locking piece 26 provided in the neck part 22 of the container 2, and the latching ratchet 36 of the inner cap 3, and is attached to the male screw 24 of the container 2. The engagement torque C by the ratchet mechanism 37 between the outer cap 7 and the inner cap 3 when the female screw 33 of the inner cap 3 is rotated in the screwing direction is the external thread ( It is set larger than the engagement torque A of the lock mechanism 35 when screwing the internal thread 33 of the inner cap 3 to 24, and the non-engagement torque of the ratchet mechanism 37 is connected to this lock mechanism 35. It is set smaller than the release torque B at the time of resisting and releasing the screwing of the container 2 to the male screw 24 by the female screw 33 of the inner cap 3. When the outer cap 7 is rotated in the direction of screwing the female screw 33 of the inner cap 3 to the male screw 24 of the container 2, the inner cap 3 can be rotated together with the outer cap 7. The locking piece 26 of the container 2 and the locking ratchet 36 of the inner cap 3 can be engaged and locked by the locking mechanism 35 to prevent falling out. At the same time, the female screw 33 of the inner cap 3 is screwed into the male screw 24 of the container 2, and the locking piece 26 of the container 2 is engaged with the latching ratchet 36 of the inner cap 3. Compared to the case where the lock mechanism 35 is used to lock the lock mechanism 35, the internal thread 3 of the inner cap 3 to the male screw 24 of the container 2 is released to release the inner cap 3 from the container 2. It can be made difficult to remove from the bend 23. Therefore, it is possible to more reliably prevent the removal of the inner cap 3 from the bent portion 23 of the container 2 by the torque balance.

<Minimum remaining amount, nozzle direction regulation>

Further, by forming each of the outer circumferential surface 39a of the protruding cylindrical portion 39 of the inner cap 3 and the inner circumferential surface 53a of the main surface portion 53 of the lowering head 5 in a radial cross-section octagonal shape, the lowering is performed. It becomes possible to position the apparatus direction of the head 5. For this reason, by positioning the apparatus direction of this push-down head 5, the container 2 can be made directional and the front side, the back surface, etc. of the container 2 can be determined, and therefore this container 2 The position of affixing such as a label on the furnace can be specified, and when the plurality of containers 2 are displayed, the directions of all the depressing heads 5 can be easily aligned in one direction, and these containers 2 are displayed. We can improve aesthetics when we do. At the same time, by forming each of the outer circumferential surface 39a of the protruding super cylinder portion 39 of these inner caps 3 and the inner circumferential surface 53a of the main surface portion 53 of the depressed head 5 in a radial cross-sectional octagon shape, Due to the fitting of the protruding super cylindrical portion 39 and the indented concave portion 54a, the pressing head 5 cannot be rotated in the circumferential direction only by applying a small force, and only protrudes when a certain large force is applied. Since the fitting of the super cylinder part 39 and the fitting concave part 54a is shifted and the down head 5 can be rotated in a circumferential direction, the suction tube installed in the lower end of the pump main body 41 of the pump 4 By adjusting the device direction of the push down head 5 in correspondence with the position, the liquid L contained in the container 2 can be discharged more reliably without leaving, and the ejector 1 in the use state It can improve the ease of use. In addition, when the inner peripheral surface 61a of the main body portion 61 of the stopper 6 is formed in a radial cross-section octagonal shape, the stopper 6 is fitted to the protruding super cylinder portion 39 of the inner cap 3 when the device is fitted. The circumferential direction is positioned, and rotation of the stopper 6 in the circumferential direction can be prevented. In addition, as the inner circumferential surface 39a of the protruding super cylinder portion 39 of the inner cap 3 and the inner circumferential surface 53a of the main surface portion 53 of the lowering head 5, the protruding super cylindrical portion 39 is applied when a predetermined force is applied. ) And the fitting recess 54a are displaced so that the pressing head 5 can be rotated in the circumferential direction.

Moreover, in the state which removed the down head 5 from the upper end of the stem 42 of the pump 4 by the fall prevention rib 39c provided in the protruding super cylinder part 39 of the inner cap 3, Since the fall out of the stopper 6 is prevented, the covering cylinder portion 76 of the outer cap 7 is also in a state where the pull down head 5 is removed from the upper end of the stem 42 of the pump 4. Since the stopper 6 cannot be removed in the horizontal direction by the cover by the cover, and the stopper 6 cannot be pulled upward by the fall prevention rib 39c, the pressing head 5 of the stem 4 After removing the stopper 6 from the upper end, the lowering head 5 is mounted again to prevent the lowering head 5 from being able to be pushed down. The unused state can be more surely maintained.

Moreover, since the axial-shaped part 44 of the stem 42 of the pump 4 is covered with the protrusion cylinder part 39, and the stopper 6 is attached to this protrusion cylinder part 39, the head which pushed down (5) is removed from the upper end of the stem 42, and the liquid L contained in the container 2 is extracted from the upper end of the stem 42 for trial use, and then the upper end of the stem 42 If the lowering head 5 is to be remounted, the upper end of this stem 42 enters into the protruding cylinder 39 of the inner cap 3, and the lowering head 5 is attached to the upper end of the stem 42. Before the stem 42 is pushed down to the position where it can be mounted, the lower end of the main surface portion 53 of the lowering head 5 comes into contact with the upper end of the main body portion 61 of the stopper 6, and the lowering is performed. Since the head 5 cannot be pushed down further, and this fall head 5 cannot be mounted on the upper end of the stem 42 again, it cannot return to an unused state again. At this time, when the pressing head 5 is removed from the upper end of the stem 42, the protruding super cylindrical portion is formed by an upper release preventing rib 39c provided on the protruding super cylindrical portion 39 of the inner cap 3. Since the stopper 6 provided in (39) cannot be pulled upward, the stopper 6 is pulled upward, and then the lowering head 5 is mounted on the upper end of the stem 42 again, and the pushing head is lowered. It is also impossible to press (5) to make the state operable. Therefore, the unused state of the sealed container 11 can be more surely maintained, and the return to the unused state after removing the pressing nozzle 5 and removing the liquid L from the container 2 can be prevented. can do.

In addition, an annular convex portion 45b is integrally provided on the outer circumferential surface 45a of the head apparatus portion 45 of the stem 42 of the pump 4, and the convex portion 45b is used to provide the head apparatus portion ( The sealing member of the push down head 5 to the mounting cylinder part 54 by 45 is prevented from being pulled out, and a seal member is attached to the head device part 45 of the stem 42 to provide a separate member such as an O-ring. Compared with the structure to prevent the removal, the number of parts can be reduced, the configuration can be simplified, and the lowering head 5 is assembled to the head unit 45 of the stem 42 to be assembled. When the convex portion 45a is shaved or crushed when deformed, the depressing head 5 is once detached from the head unit 45, and then the depressing head 5 is removed from the head unit 45. , The lowering head 5 is hard to be prevented from falling out of the convex portion 45a, and the lowering head 5 (5) a can be prevented more surely using the test of the liquid (L) in the container (2) due to detaching from the upper end of the stem (42). In addition, since the pump cannot be freely detached, it is also impossible to remove the pump and mix foreign substances.

In addition, the upper side of the outer surface of the main body portion 71b of the outer cap body 71 covering the outer cap 7 is formed as an upper-subtracting mold (not shown), and the lower side of the upper surface of the main surface portion 71b is formed. Since the outer cap 7 can be formed by a combination of three molds in total, by making the inner side of the outer cap 7 into a shaft diameter mold (not shown) which can be reduced in diameter as a lower-subtracting mold (not shown), The mold configuration of the outer cap 7 can be simplified, and the manufacturing of the outer cap 7 can be facilitated.
